Hi!
I set up the standard "date and name based" permalink structure (second in the "common options" in the permalink admin page), and when I click on "update", the radio button checked changes to the "Custom, speficy below" automatically. The structure there is, by default,:
/blog/%year%/%monthnum%/%day%/%postname%/
Don't know if this is normal, but, anyway, there seem to be no problems with all the permalink except for the link to the "comments feed". No matter what theme I use, every time I click on the "comments feed" it says "page not found". The link goes to "/comments/feed/" after the root address of the website.
I'm using the Bionic Jive template, right now, and it uses the standard "bloginfo('comments_rss2_url')" link. I can't understand why all the others link to syndication feed are working... Can anyone help me? Thanx! =)
